Access point association and tracking of physical addresses

ABSTRACT

Disclosed in various examples are methods, systems, devices, and machine-readable mediums used for identifying and tracking device and access point geographic locations of wireless (e.g., Wi-Fi) networks. In an example, operations performed by an infrastructure system for provisioning location information include: receiving access point identification information (e.g., a MAC address) that identifies an access point of a wireless network; validating the access point identification information in a list of known wireless networks (e.g., a whitelist); determining an assigned location corresponding to the access point; communicating an indication of the assigned location to the device; and facilitating a communication session with the device, using the wireless network, as the communication session uses the indication of the assigned location by the device. Further operations involving administrator involvement and approval of the location, and client use of the whitelist and the assigned location information, are also disclosed.

RELATED APPLICATIONS

This application is a continuation of prior U.S. patent application Ser. No. 16/044,180, filed on Jul. 24, 2018, titled “ACCESS POINT ASSOCIATION AND TRACKING OF PHYSICAL ADDRESSES,” which is related to U.S. patent application Ser. No. 16/043,932, titled “DEVICE-BASED ACCESS POINT ASSOCIATION AND TRACKING OF PHYSICAL ADDRESSES,” filed on Jul. 24, 2018, the contents of which applications are incorporated herein by reference in their entirety.

BACKGROUND

With the widespread deployment of wireless networks and portable computing devices, a computing user may frequently operate their computing device at different locations. For instance, a user may choose to utilize a notebook computer, tablet, smartphone, or other mobile computing device at an airport, home, restaurant, remote worksite, or many other private or public locations.

The mobility of computing devices and the increased prevalence of wireless network connectivity has added complexity to a variety of real-world communication scenarios, especially scenarios involving location-based services. As one example, a computing device may have robust wireless network connectivity and have the potential to establish a voice-over-IP (VoIP) call over the Internet with an emergency call service, such as a “911” calling service in the United States, from many different locations. However, if such a call is made over many VoIP services, the emergency call service is unlikely to know the location of the originating call and the computing device. This limitation is also reinforced when the computing device does not include built-in location features such as GPS sensors, and where the wireless network is not aware of (or has not been provisioned with) its own location. As a result, regulatory requirements have been proposed or enacted in some jurisdictions to block emergency calls from VoIP clients entirely, to prevent emergency responders from being dispatched to an incorrect or incomplete location.

DETAILED DESCRIPTION

Disclosed in some examples are methods, systems, devices, and associated operations and functionality that enable location tracking of wireless network clients, through the use of coordinated network service and client operations. The location tracking techniques discussed herein may be applicable to perform a variety of location-based services and communication activities, including but not limited to the use of location tracking and identification with emergency call services.

In an example, network service and client scenarios are disclosed which involve devices that report MAC (Media Access Control) addresses of connected or nearby access points (APs) to a network infrastructure service. The network infrastructure service maintains a list of MAC addresses or other access point identifiers, which are used to validate and authenticate the reported APs. When identifying a newly reported AP, the network infrastructure service operates to determine, assign, and track a location to the newly reported AP, based on a known location of the VoIP client that reported the new AP, based on proximity of the VoIP client to other known APs, based on a response from a network administrator which provides the location, or based on other dynamic or real-time factors. The network infrastructure service may also utilize this list of MAC addresses or identifiers to validate the reliability or validity of the newly reported AP, and implement aspects of network selection, validation, and fraud prevention.

In further examples, the list of MAC addresses or other identifiers may be provided or maintained in a whitelist. This white list, maintained and synchronized between the network service and the client, may define a list of registered (e.g., tracked, validated, trusted) APs for network connectivity or network services. The use of a white list may involve both client and server coordination, such as by having MAC addresses that are pushed to respective clients become white-listed or distributed based on a specific user, account, service, device, or the like. The location tracking and provisioning techniques may also be extended so that if a new AP is verified (e.g., by an IT administrator), the new AP may be automatically added and provisioned in a white list for a user or a group. Additionally, the location tracking and provisioning techniques may also enable the device to become aware of its location when connected with or in range of a particular AP. As a result, if the client conducts a subsequent communication session, such as with an emergency call service, the client can provide this location to the service.

Use of the present techniques may provide a number of improvements and efficiencies in network operations and location services. First, the techniques enable an AP or wireless network to be quickly associated with a particular location (or area encompassing the location) on the basis of what other nearby APs have been detected. Second, the techniques enable an AP or wireless network to be easily verified and associated with a location by actions of a network administrator, such as in response to use of a newly deployed AP, moved or reconfigured AP, or other settings where location or service configurations were overlooked or incomplete. Third, the techniques improve both client-side and network service-side security, to prevent clients from using rogue or unauthorized APs and wireless networks.

The present disclosure thus addresses issues with computer networking in which the location of access points and clients associated with such access points are unknown, not updated, or are inaccurate. The present techniques provide technical solutions and benefits that are applicable for location-based services, networking services and systems, network administration services and systems, and client devices. The disclosed techniques improve the functioning of the computer system by enabling use of additional services and may be accompanied by security and communication functionality improvements for both network and client software. These and other benefits will be apparent from the following examples and illustrations.

FIG. 1 illustrates an example deployment 100 of access points for communication operations, according to some examples of the present disclosure. Computing device 110, shown as a cellular telephone, and computing device 130, shown as a notebook computer, are portable computing devices capable of operating at different locations. Specifically, devices 110, 130 may be moved among different locations of a corporate, personal, or other network deployment provided by various network access points 116, such as APs 116-A, 116-B, 116-C, 116-D, 116-E, 116-F.

In an example, the network APs 116 operate according to Institute for Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) protocol specifications, and broadcast access point information for discovery and connectivity by clients. This access point information may be provided in a respective beacon frame, and include a Media Access Control (MAC) address, and/or a Service Set Identifier (SSID) of the network. In other examples, the access point information may be provided in other control channels and messages, such as specified via 802.11 action frames, or channel measurements such as specified by 802.11k radio resource measurements. Other data fields or messages may also be communicated, broadcast, or provided, in accordance with the parameters of the employed network protocol and standard.

In an example, the computing devices 110, 130 are provisioned with a white list of access points (e.g., access points that the device is permitted to connect to, or use, to perform some operation). This white list may be provided to the devices 110, 130 as a result of network configuration (e.g., by joining a network domain), or provided as a result of use or association with a service, such as a network communications service 120. In a further example, the white list may be maintained and distributed to the computing devices by the network communications service 120 when the computing devices 110, 130 respectively join, register, or authenticate with the network communications service 120.

The network communication service 120 provides voice, video, or other communication functionality with other devices and users as part of a Voice-over-IP (VoIP) calling service. In a further example scenario, discussed in more detail in FIG. 2, the VoIP calling service implemented by the network communications service 120 includes functionality to perform calls with conventional telephone services, including emergency calling services.

Additionally, as shown in limited detail in FIG. 1, other devices or components may be used to relay or extend communications to other devices and device components. For example, a peripheral headset 132 (e.g., a wired or Bluetooth wireless headset) may be used to exchange audio of a communication session (e.g., a call) between a human user (not shown) and the computing device 130. However, it will be understood that the techniques discussed herein are not limited to a particular form factor of the devices 110, 130 or any peripheral or software client used with the devices 110, 130. Likewise, the techniques discussed herein are not limited to phone or voice calls but may extend to a variety of types and forms of communications.

The computing device 110, 130 may scan for beacons broadcast by the access points 116. The computing device 110, 130 may then connect to a respective access point through an association and authentication process (e.g., as outlined by the IEEE 802.11 family of standards). After connecting to the access point, software on the computing device 110, 130 may temporarily restrict network access to some applications or services on the computing device 110, 130. The computing device 110, 130 may establish an encrypted tunnel and send an access point report with scan results, to the network communications service 120. The scan results may include access point information (e.g., MAC addresses) corresponding to any of the access points 116 and may include a listing of APs currently in range. The scan results may be communicated to the network communication service 120 when logging into the service, when performing an action (such as initiating a certain type of call) with the service, at various time intervals, etc.

In further examples, the access point information may include a geolocation (e.g., geographic coordinates or identifier) of the computing devices 110, 130 and/or measurements of a radio signal from the access points, if known and available. The network communications service 120 may utilize the information provided by the computing devices 110, 130, to associate the respective devices with observed location of the access points in the report. The network communications service 120 may utilize the information provided by the computing devices 110, 130 to associate the device with tracked locations of the APs 116, including to establish, update, or verify the location and operational status of a particular AP or a particular device (or sets of APs or sets of devices). This information may be combined or considered in addition to AP or device location information already maintained by or available to the network communications service 120.

The network communications service 120 may store and track a plurality of locations of computing devices and access points. The network communications service 120 may perform this tracking as part of a white list maintenance service, which maintains user-based or device-based white lists to track locations and validation status of various APs, networks, and network services.

In addition to access point information directly provided from the devices 110, 130, the network communications service 120 may utilize stored one or more other previously received reports and information from other computing devices, other access points, an administrator, or other location services, to calculate a location of the access points 116. This information may include observed measurements of wireless network signals taken by a computing device (e.g., a received signal strength indicator (RSSI), a round trip time, a time of flight measurement, or the like). For instance, using such measurements, the network communications service 120 may compute a distance between the respective computing device and each observed access point, or an estimate of the proximity of an access point to existing known access points. Using additional reports from additional computing devices, or changed network conditions, the network communications service 120 may employ a trilateration or other location refinement algorithm to calculate or refine an observed position of the access points.

As an operational example, suppose that computing device 110 includes an AP white list which allows the device 110 to connect to APs 116-B, 116-C, 116-D. When the computing device 110 is in proximity to the AP 116-A, the device 110 will determine from the white list that it is not allowed to connect to the AP 116-A. Or, if the computing device 110 is allowed to connect to the AP 116-A, the device 110 will determine that it cannot perform some action or service via the AP 116-A. In response, the computing device 110 contacts the network communication service 120 to validate the use of the AP 116-A, and to provide the network communications service 120 with access point information regarding the AP 116-A and other visible APs (e.g., APs 116-B, 116-C, 116-D). The network communications service 120 requests that an administrator (not shown) validate the use of the AP 116-A for the requested connectivity or service. Upon approval, the network communications service 120 updates a white list at the network communications service 120 and/or at the device 110, which enables the device 110 to connect to or use a service with the AP 116-A.

Also, as an operational example, a geographic location associated with a new AP may be associated or correlated with a geographic location known for other existing known APs. Suppose that computing device 130 connects to AP 116-E, located at latitude E and longitude E, and the AP 116-E is not yet included on a white list. The computing device 130 reports the access point information of multiple nearby access points, including information for AP 116-E in addition to information for AP 116-F. The network communications service 120 maintains geographic tracking information for AP 116-F, associating the AP with latitude F and longitude D. The network communications service 120 may derive an approximation of the location of AP 116-E—here, by identifying that the maximum range 122 of the AP 116-F extends to latitude D, but the maximum range 124 of the AP 116-E does not extend to the location of AP 116-F at latitude F; thus, the range of AP 116-E must end between latitude F and latitude D. Other network location calculation techniques involving the devices 110, 130, the APs 116, and other equipment are also usable with the present techniques.

In further examples, other computing devices within a predetermined proximity to a subject computing device may also be identified as located within the same cluster or group. For instance, in a corporate building setting, where a large number of devices and access points are located and concurrently operating, fewer measurements from devices and APs may be needed to calculate a position of the access points. Additionally, the location information that is derived from administrator and network configurations (e.g., devices on the same domain or network) may also assist the identification of devices within a cluster or group.

The network communications service 120, in further examples, may include or coordinate with aspects of a fraud detection service. For example, the fraud detection service may conclude that the position of AP 116-A at latitude F and longitude D is not consistent with a previously recorded position, or that a device at a location which sees APs 116-A and 116-C is not expected to see AP 116-F. In such cases, an access point which is not operating with expected characteristics may be labeled as potentially anomalous, and information may be communicated to an administrator to determine remedial actions, including, removal from a white list, addition to a black list (prohibited list) or gray list (a list requiring verification), notification to an administrator, or other actions.

Further, a fraud detection service operating at the network communications service may utilize access point information and related signal or location measurements to determine what other access points should be visible to the computing device based upon the access point positioning data. Accordingly, a position of the computing devices 110, 130 may be ascertained from the measurements and the known positions of the access points 116 from all or portions the access point positioning data, including positioning data collected over a period of time. In other examples, the fraud detection service may use only the observable access point information communicated by the computing device.

Additionally, the access point information collected by the computing devices 110, 130 may provide positioning data for use in a model that, when given a list of one or more visible access points, outputs a probability that another given list of one or more access points would be visible. For instance, the computing device may calculate the probabilities of each visible access point given all other visible access points. This model may be created based upon a access point information collected over time from a plurality of other computing devices. Other variations to fraud detection, location identification, and access point verification may also be used in combination with the location identification techniques discussed herein.

In another example, the present location tracking techniques may be used with cellular base stations, repeaters, and other cellular network equipment stations. For instance, various types of microcell stations, picocell stations, or home repeaters may be deployed in various geographic areas in the same manner as the Wi-Fi access points indicated in FIG. 1. Accordingly, the references herein to “access points” may refer to cellular network stations, and “access point information” may refer to information obtained from cellular network stations, such as in networks operating in accordance with a 3G, 4G/LTE, or 5G specification. With such cellular network deployments, the access point information may include base station identifying information that is communicated on a broadcast or control channels (e.g., FACCH (Fast Associated Control Channel), or SACCH (Slow Associated Control Channel)).

Turning now to FIG. 2, an example sequence 200 of access point location tracking is illustrated, performed with a communication session according to various examples of the present disclosure. The operations of the sequence 200 may be performed by aspects of a client device 212, an access point 202, a VoIP network communications service 220, a network administration service 230, a voice network location information service 250, and other services and functionality discussed herein.

At operation 208, a set of network access points visible to a client device 212 may be determined, as the client device 212 receives and parses identification information from one or more access points. For example, the client device 212 may scan one or more frequencies for beacon or other broadcast frames that advertise access points (e.g., the AP 202). These beacon frames may include an access point identifier or information such as a Service Set Identifier (SSID), a MAC address of the access point, and the like. In some examples, in addition to scanning one or more channels for one or more access points, the client device 212 measures a metric corresponding to the channel that is indicative of a distance between the computing device and the access point. For example, such metric may include a received signal strength, a round trip time, a time of flight measurement, or the like.

The client device 212 is adapted to host a white list 214 used for determining connectivity or capabilities of a particular AP. The white list 214 may also include a list of known geographic locations as determined by the network communications service 220 or another entity. Also in an example, the client device 212 may determine whether to perform a geographic information operation 206, to request geographic information of the AP based on information available or maintained in the white list, such as time/date information that may indicate the geographic information is outdated.

With the geographic information operation 206, the client device 212 provides a geographic information request to the VoIP network communications service 220. This information request may be performed in connection with joining or authenticating with a communications service, attempting to conduct a call, at regular intervals, etc. In an example, the geographic information request is performed using connectivity via the AP 202. However, another access point (or, another network connection or topology, such as a 3G/4G/5G wide area network connection) may be employed. The operation 206 concludes with a geographic information response being returned to the client device 212 from the VoIP network communications service 220. This geographic information response may include an indication of a specific geographic location of the AP 202 or the wireless network, such as GPS coordinates, street address, building identifier, etc.

The operations used to generate the geographic information response, and to determine missing geographic information, are further depicted in FIG. 2. For instance, if the VoIP network communications service 220 does not have geographic information for the AP 202, and is unable to determine this information from the access point identification information, then further information may be obtained from an external source or entity. This may include the use of an administration query to a network administration service 230, in administration query operation 216.

The network administration service 230 may operate a server platform 232 maintaining network and device data 234 for various devices and entities within a network managed by administrator 240. For instance, the administrator 240 may define an access point list 236 which serves as a white list for an organization or company, and which includes or is associated with administrator-known/maintained location information. Further, if the location information for a particular AP is not known or maintained, the administrator 240 may be queried to supply the location information. Other uses of external data services and location services to identify the location of the client device 212 and the AP 202 may also be employed with the use of the network administration service 230.

Based on the geographic information operation 206, a communication session 204 may be established. This may include use of the VoIP network communications service 220 to establish a call with location service capabilities. This call is shown with use of communication session 218, and the call is established between the network equipment 222 of the VoIP network communications service 220 and the network equipment 262 of the communication destination 260.

In an example, the communication session 204 facilitates an emergency call, or a like call that involves the use of a voice network location information service 250. For example, the voice network location information service 250 may include processing equipment 252 which collects or processes location information, such as in an “enhanced 911” setting. In an example, geographic information established for the AP 202 by the VoIP network communications service 220 is communicated to the voice network location information service 250 and the communication destination 260 in communication session 218. This communication session 218 may be used to facilitate the call to exchange voice, video, data, or other information between the user 210 of client device 212, and a destination user 270 of the network equipment 262 (including, via use of communication peripheral equipment 272). While FIG. 2 and other examples herein describe the use of a geolocation determined by the methods herein in the context of a voice call, the geolocation may also be utilized in other types of data applications and location services.

FIGS. 3-6 describe additional methods for performing the operations depicted in FIG. 2, from client-side perspectives (FIGS. 3 and 4) and communication server-side perspectives (FIGS. 4 and 5). Each of the methods of FIGS. 3-6 may adapt to different amounts of information available within the overall system, such as different types of access point positioning data and whether measurement and/or computing device locations are available. It will be understood, however, that different client and server run-time scenarios may involve the different combinations of the depicted operations.

FIGS. 3-4 specifically depict flowcharts of example methods performed by a client device for access point location tracking. As shown, the flowchart 300 of FIG. 3 commences with a client device, in operation 310, identifying access point information from a particular wireless network (or, from available wireless networks in reception range). For instance, this access point information may comprise an SSID, a MAC address, or another identifier of the access point(s) within wireless range. Using this access point information, the client device performs, in determination 320, an evaluation of whether the location information for a particular wireless network (and access point) is maintained by the client device in a white list. If the location information is available, the flowchart 300 progresses to utilizing the location information in a communication session with a destination device or service, in operation 390.

If the location information is not available, then further processing is performed in the flowchart 300 as follows. The client device continues to verify one or more services for the wireless network, in operation 330, such as whether permissions are available to utilize a particular network service. The client device also continues to request location information of the wireless network or access point, in operation 340, from a communication service.

A further evaluation, in determination 350, is performed by the client device (and, potentially, the communication service), to identify whether location information is maintained for the wireless network or access point by the communication service. If this location information is already maintained and available at the communication service (e.g., in a communication service white list), then the client device obtains the location information associated with the access point, in operation 360. The flowchart 300 then concludes with the client device utilizing the location information to conduct a communication session with a destination device or service, in operation 390. If this location information is not maintained or not available at the communication service (e.g., is not stored or tracked by a communication service white list), then operations are performed to obtain the location information from a network administrator or a network administrator service, in operation 370. This location information is then stored at the communication service, in operation 380, such as in the white list. The operations of the flowchart then conclude with operations 360, 390 to communicate the location information to the client device and utilize the location information.

FIG. 4 provides a sequential list of operations used for determining access point geographic locations, from a perspective of a client device. The flowchart 400 of FIG. 4 commences with an optional operation of connecting to an access point associated with a wireless network, in operation 410. In an example, the access point is used for initial network connectivity (e.g., internet connectivity) to access a network communications service (e.g., a VOIP service) which provides an access point geographic location and validation status for the access point and wireless network. However, some of the following operations may occur using a connection to another wireless network (e.g., a secondary network, public network, wide area network, etc.), and subsequently connecting to the access point associated with the wireless network after receiving a geographic location and a validated status (e.g., after operation 440, discussed below).

The operations of the flowchart 400 continue by receiving or otherwise obtaining the access point identification information from the wireless network, in operation 420. This identification information identifies the access point of the wireless network, and may include a SSID, MAC address, or other identifier of the access point. In further examples, the MAC address is received as an encrypted value. Also in further examples, the access point identification information includes a certificate issued for the wireless network. In various examples, the wireless network operates in accordance with an IEEE 802.11 standard; whereas in other examples, the access point is a cellular network station operating according to a cellular network standard, and the access point identification information includes identifier information for the cellular network station.

The flowchart 400 continues with the comparison of the access point identification information with information stored at a device white list, in operation 430. In an example, this comparison results in identifying an unvalidated status of the access point of the wireless network, from a white list maintained at the device (e.g., stored in a memory of the device) that includes identification information of at least one validated access point. In further examples, the white list is synchronized with and updated from the network communication service, including in an on-demand fashion when a particular communication service or unknown access point/wireless network is attempted to be used. Other forms of black lists, gray lists, and permission lists for services, networks, or individual access points may also be utilized and maintained (e.g., synchronized) at the device. In a further example, comparing the access point identification information with the white list, is performed by evaluating at least one characteristic of the wireless network with at least one characteristic stored in the white list. This at least one characteristic stored in the white list may relate to at least one of: identifiers of wireless networks operating in proximity to the wireless network; a number of wireless networks operating in proximity to the wireless network; service information associated with the access point; vendor information associated with the access point; or location information associated with the access point.

The flowchart 400 continues with the communication of the access point information to the network communication service, in operation 440; and the receipt of a white list (or an update to a white list) and an indication of a geographic location of the wireless network from the network communication service, in operation 450. The indication of the geographic location may also be accompanied by a validated status for the wireless network, the access point, a particular service, or the like. Based on this received information, the white list at the client device may be updated to include at least one identifier of the access point of the wireless network (and any accompanying service, network, or information status, such as a validation status).

In an example, the network communications service maintains a mapping of the access point identification information to a geographic identifier. For instance, the indication of the geographic location that is communicated to the client may include a specific geographic identifier; also for instance, the geographic identifier may include at least one of: global positioning system (GPS) coordinates, a street address, or a building identifier. In still further examples, the indication of the geographic location includes information that is obtained from an administrator associated with the wireless network. Accordingly, the indication of the geographic location (e.g., the geolocation of the access point, and thus, the device connected to the wireless network via the access point) may be provided to the device by the network communications service, in response to a determination by the network communication service that the access point identification information is associated with a defined geographic location.

The flowchart 400 continues with operations to initiate, or otherwise perform, a communication action in the network communication service, using the wireless network, in operation 460. This communication action may occur in response to receiving the indication of the validated status and the indication of the geographic location. This is followed by further operations, conducted as part of the communication action, to provide the geographic location for the wireless network from the device to a communication destination (a destination service, device, or system), in operation 470.

The operations of flowchart 400 conclude by performing a communication action with a destination service, device, or system, in operation 480. In an example, the communication action includes performing a voice over IP (VOIP) call, based on a communication session facilitated for the device using the network communications service. In a further example, the communication destination is an emergency calling service. For instance, the communication session may enable an emergency call between the device and the emergency calling service, as the communication session is used to associate the emergency call with the geographic location for the wireless network.

FIGS. 5-6 also depict flowcharts of example methods performed by an infrastructure service for access point location tracking. As shown, the flowchart 500 of FIG. 5 commences with a service (or server-side) device, in operation 520, receiving access point information and other characteristics of a particular wireless network or particular access point from a client device. Again, this access point information may include a SSID, a MAC address, or another identifier of one or more access points. In optional examples, the server performs fraud verification of received access point characteristics, at operation 530, using this access point information. For instance, the integrity verification may determine whether the SSID or MAC address is being spoofed, whether the access point is in a correct operational state, or other aspects of verification and validation.

The flowchart 500 continues with a determination, in evaluation 540, which identifies whether the wireless network AP is included in a white list maintained by the service. If the wireless network AP is not included in the white list, then approval for the wireless network AP is requested from a network administrator, in operation 550. This leads to a further determination, in evaluation 560, based on whether the wireless network AP is approved for use by the administrator. If not approved, then location information for the device and AP is denied, in operation 505.

If, however, the wireless network AP is included in the white list or is approved by the network administrator for inclusion in the white list, then the flowchart 500 continues with a determination of whether AP location information is available, in evaluation 570. If the AP location is not available (or is outdated or restricted), then a further determination is performed in evaluation 580, on whether the location is available from other APs or devices, in evaluation 580. As a result, if the AP location information is available, such location information may be included in the white list and provided to a client device, in operation 515.

FIG. 6 includes a flowchart with a sequential list of operations used for determining access point geographic locations, from a perspective of an infrastructure service. The flowchart 600 of FIG. 6 commences with operations of receiving access point identification information for a wireless network, via a subject device, in operation 610. This is followed by comparing the access point identification information to stored identification information, in operation 620. In an example, the access point identification information includes a SSID or a MAC address of the access point, as the wireless network operates in accordance with an IEEE 802.11 standard.

The flowchart 600 of FIG. 6 continues by querying an administrator or network service for a geographic location associated with the access point identification information, in operation 630. From this information, the service obtains a defined geographic location associated with the access point identification information, as in operation 640. The access point identification information is then validated to an assigned location, in operation 650.

The flowchart 600 of FIG. 6 concludes by communicating the assigned location to the device, in operation 660, and facilitating a communication session involving the device, based on use of the assigned location, in operation 670. In an example, the communication session with the device is initiated in response to verification of the assigned location by the device. In an example, the access point identification information identifies the access point of the wireless network to which the device is already connected, whereas in another example, the access point identification information identifying the access point of the wireless network to which the device will attempt to connect. Accordingly, the techniques of flowchart 600 may be implemented in both current and prospective connection settings.

The white list functionality 780 may identify access points by an access point identifier that may comprise one or more of: an SSID, a MAC address, or the like.

For instance, network scanner functionality 790 of the network interface 785 may scan for one or more access points, by listening at designated frequencies and according to designated protocols such as an 802.11 protocol for beacon frames sent by access points. In various examples, the network scanner functionality 790 may disregard access points that are not in the white list based upon the identification of the access point in the white list. Also in some examples, the network scanner functionality 790 may perform one or more measurements of the radio interface between the access points that are scanned and the computing device. For example, such measurements may include a received signal strength (which may be described by RSSI), a round-trip time, and the like. In some examples, the network scanner functionality 790 may associate and/or authenticate with one or more access points to perform the measurements.

To control the connection or use of the computing device 765 with an access point, the network access restrictor 795 may restrict the network access of the computing device 765 (for all connectivity or for a particular service or protocol) until the subject access point has been added or authorized to a white list by the white list functionality 780.

The computing device 765 includes location identification functionality 770 which may be used in some examples to determine location from other sources. For example, this location identification functionality 770 may include a global positioning system (GPS) sensor, address lookup table, or other operable components related to location. In other examples, relevant location identification operations are performed by the access point or network communications server (as discussed below).

The wireless access point 750 is depicted in FIG. 7 as including communications functionality 755 and location identification functionality 760. The communications functionality 755 may facilitate respective connections with client devices (such as computing device 765) and the establishment of local and wide area network capabilities, such as using an IEEE 802.11 protocol.

The fraud detection service 720 may detect improper credentials or characteristics of access points or devices for connectivity, based on the location information database 702 and the access point information database 704. The location identification service 715 may include functionality to identify an approximate or estimated location of the wireless access point 750 or the computing device 765 through derived location information on nearby access points, devices, landmarks, network infrastructure, or measurements, including those maintained by the location information database 702 and the access point information database 704.

Finally, the network administration server 730 is depicted in FIG. 7 as including a fraud verification service, a network domain service interface 740, and an administrator control interface 745, operating with use of a location information database 706. The fraud verification service 735 may enable an administrator to verify access point information, including location information or identifiers, using a white list or predefined administration information or as stored in a location information database 706. The network domain service interface 740 may operate to define network operational domains and services via the wireless access point 750 or sets of access points. The administrator control interface 745 may receive location information and control parameters for devices, access points, and the network domain, consistent with the administrator functionality discussed above.
